OpenSCAD - Frequently Asked Questions
Frequently Asked Questions about OpenSCAD
Why is my imported STL file appearing with F5 but not F6?
When an STL file appears in the preview mode (F5) but not in the full render mode (F6), it is often due to issues with the STL file itself. The most common problems include “bad STL files” or “zero faces” where all three points of a triangle are on the same line. To resolve this, you can use tools like Blender, MeshLab, or NetFabb to verify and fix the STL file. The preview mode simply draws the triangles without performing full geometry calculations, which is why the model might appear in preview but not in render mode.
What does the “Unsupported DXF Entity” warning mean when importing DXF files?
This warning occurs when the DXF file contains features that OpenSCAD’s importer does not support, such as Bezier curves or splines. To avoid this, you can convert Bezier curves to short line segments using Inkscape’s “Extensions -> Modify Path -> Flatten Beziers” feature. This ensures that the DXF file only contains entities that OpenSCAD can handle, preventing incomplete models.
